Chlamydia, specifically Chlamydia trachomatis, is classified as a gram-negative bacterium. This means that it does not retain the crystal violet stain used in the gram staining procedure, which distinguishes between gram-positive and gram-negative bacteria.

Chlamydia trachomatis is an anaerobic, intracellular organism that replicates within eukaryotic cells. Its gram-negative classification aligns with its physiological characteristics as it has a unique cell wall structure that does not take up the dye typically retained by gram-positive bacteria.

For more detailed information about Chlamydia trachomatis, you can explore the following resources:

• The NCBI Bookshelf provides comprehensive insights about Chlamydia trachomatis, confirming its status as a gram-negative bacterium. Read the NCBI article.

• The Wikipedia page on Chlamydia trachomatis also verifies that it is a gram-negative, anaerobic bacterium. Visit the page here.
